The Moon and Planets

Last thread derail I promise.

If anyone can point me to some websites, you tubes that would be interesting to a 6 year old I would be forever in your debt (especially on a Friday night).

Try the cartoon Planet Cosmo, about a family exploring the solar system.

I bought this at Xmas, a Skymax 150 "Maksutov" Telescope. So far I've only seen Jupiter but that was (to a nerd) pretty exciting, to see planet with my own eyes instead of on Google



Have a look at https://www.astrobuysell.com/uk/browse.php now and then, bargains come up.

With that, you should be able to pick out the polar caps on Mars and a couple of the rings of Saturn. I have to admit that Saturn is my favourite planet to view simply because of the rings.

Open to correction, but I read in my kids book (which is a great read) that to travel from one side of The Milky Way Galaxy in a rocket doing approx 10,000 mph it would take 3,000,000 years

I think it’d be closer to 6 billion years.

6.7Bn with the Milky way being an estimated 100,000 ly across and you started at the edge and could maintain constant velocity (which you won't due to gravitational interactions).

It’s facts such as these that help crystallise just how vast even our local vicinity is.

Whenever life gets you down, Mrs. Brown
And things seem hard or tough
And people are stupid
Obnoxious or daft
And you feel that you've had
Quite enough
Just remember that you're standing
On a planet that's evolving
And revolving at nine hundred miles an hour
That's orbiting at nineteen miles a second
So it's reckoned
The sun that is the source of all our power
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at four hundred thousand miles an hour
In the galaxy we call the Milky Way
Our galaxy itself contains a hundred billion stars
It's a hundred thousand light years side to side
It bulges in the middle, six thousand light years thick
But out by us, it's just a thousand light years wide
We're thirty thousand light years from galactic central point
We go 'round every two hundred million years
And our galaxy is only one of millions of billions
In this amazing and expanding universe
The universe itself keeps on expanding and expanding
In all of the directions it can whizz
As fast as it can go, of the speed of light, you know
Twelve million miles a minute and that's the fastest speed there is
So remember, when you're feeling very small and insecure
How amazingly unlikely is your birth
And pray that there's intelligent life somewhere out in space
'Cause it's bugger all down here on Earth.

My grandchildren were fascinated to discover that you can visit the moon and Mars on Google Earth on my PC, as well as view the stars and glaxies.

That bit oughtn’t have made it in, the sun isn’t the source of all of our power.

Are you referring to geothermal energy?

Geothermal, nuclear and tidal. None of these use energy from the sun.

Hmmm. Without energy from the sun, the water on the surface of the planet would not be liquid. Therefore, there wouldn't be any tidal energy. Not to any useful degree. So while the Moon may be responsible for the tides, that is only possible because of energy from the sun.

Moon related. I went to a talk by Buzz Aldrin and it really struck me that beyond a pilot/astronaut he was insanely intelligent. I'm quite sure they all were and no doubt astronauts still are to this day.

It's worth having a read of a few astronauts biographies. For recentish ones Tim Peake and Chris Hadfield are good examples, they need to be very good allrounders and the amount of training is insane. But focusing on the moon and the Apollo days, there were a lot more unknowns so they had to be ready for anything. Mike Collins and Gene Cernans are very good but there's loads I've not read. I think Eric has read most of the Mercury/Gemini/Apollo biographies and can probably advice on the best.
